On the flight to Coruscant, Luke approached Harry and propositioned him: some Jedi training. Luke sensed force strength in Harry. He could be the first Jedi of the new order, just after a bit of training. He had to be careful so that the Harry did not fall down and embrace the Sith order. It had been a very long time since there had been someone that strong in the force.
But you see it wasn't so bizarre. Harry's world and Luke's world are just alternate histories of each other. They both have midichlorians; however in Harry's universe, their power manifested as magic (and children with abnormally high midichlorians are possible, even from muggles).
Luke walked into Harry's space chambers and, ignoring his clear discomfort, said, "Hey sexy bitch, you wanna learn something really cool?"
Harry looked him up and down, sputtering, "Well—erm—"
"Cool, get your pants on you sneaky little twink-muffin."
Harry reluctantly followed him out of the room and entered the other space chamber that Luke had previously set up for him. There, he encountered many different devices: a little round ball spewing light laser beams, a few metal hilt like devices, a spikey dildo, multiple blasters, a crossbow blaster, a seeming interrogation device, and some holocasters.
"Let me teach you about the force, Harry. It is what makes us who we are. If you embrace it, the world will be no more than a simple extension of yourself."
"What do you mean?" Harry asked.
"I mean if you learn your strength in the Force, you will have some measure of control over the world."
"Just like magic," Harry whispered under his breath.
Luke then took Harry, and he brought him fully into the room. "Alright, catch." He said tossing a newly developed (by Luke of course) rainbow lightsaber.
The boys then began to spar. Hours upon hours of clashing sabers, sweat covered gazes, beautiful arcing moves. Harry began to realize some sort of odd power. Blocking Luke's furiously powerful moves was becoming easier. As if he was able to sense the moves coming, as if something was enhancing his natural strength and power.
Harry was close to victory. His strikes were becoming more and more powerful and brutal. He was about to win but, alas, Luke stuck his hand out and began to move his fingers in a squeezing motion. Harry could suddenly feel his anus expand and contract suddenly, distracting him and allowing Luke to pounce. "Welcome to the force, Harry." Luke said, pulling Harry's pants off; Harry didn't resist, but rather accepted it.
